Guide
  • For high power lasers use concave substrates (LCBS) suitable for Laser resonator applications.
  • WEB Reference Catalog Code/W3143
Remark -
Attention
  • The back side of the substrate has a ground surface; it is not usable for transmission. For transmission we recommend plano concave lenses (SLB-N).
  • WEB Reference Catalog Code/W3050
  • For cold-mirror or partial reflection application, please contact our Sales Division for a concave mirror on the back side polished.
  • The outer edge of the concave surface is chamfered, the thickness of the edge varies therefore use the back side of the substrate as datum.
